Subject: [PATCH] fix(autocomplete): apply virtual focus to first item on IME
 composition input

useAutocomplete only called focusFirstItem() when inputType was
'insertText'. IME-based input (CJK languages) reports
'insertCompositionText'/'insertFromComposition' instead, which fell
through to clearVirtualFocus(true), so the first matching item never
received virtual focus and Enter could not select it.

Closes #10126
